Sulphonyliso(thio)urea derivatives as herbicides

ABSTRACT

The invention relates to new sulphonyliso(thio)-urea derivatives of the general formula (I) ##STR1## in which R 1  represents an optionally substituted radical from the series comprising alkyl, aralkyl, aryl and heteroaryl, 
     R 2  represents an optionally substituted and/or optionally fused 6-membered aromatic heterocyclic radical containing at least one nitrogen atom, 
     R 3  represents an optically substituted aromatic or heteroaromatic radical, 
     X represents oxygen or sulphur and 
     M represents hydrogen or an equivalent of a metal, 
     and adducts of compounds of the formula (I) with strong acids, processes for their preparation, and their use as herbicides.

This is a division of application Ser. No. 769,272, filed Aug. 23, 1985, now allowed.

The invention relates to new sulphonyliso(thio)-urea derivatives, an inventive process for their preparation and their use as herbicides.

Various isoureas and isothioureas have been disclosed as potential herbicides, but have hitherto not found major importance as agents for combating weeds and/or regulating plant growth (compare DE-AS (German Published Specification) 1,138,039 and British patent specification No. 1,202,736).

New sulphonyliso(thio)urea derivatives of the general formula (I) ##STR2## in which R¹ represents an optionally substituted radical from the series comprising alkyl, aralkyl, aryl and heteroaryl,

R² represents an optionally substituted and/or optionally fused six-membered aromatic heterocyclic radical containing at least one nitrogen atom,

R³ represents an optionally substituted aromatic or heteroaromatic radical,

X represents oxygen or sulphur and

M represents hydrogen or one equivalent of a metal,

and adducts of compounds of the formula (I) with strong acids, have now been found.

If M represents hydrogen, the general formula (I) represents the individual tautomers of the formula (Ia) and (Ib) ##STR3## in which R¹, R², R³ and X have the abovementioned meanings, and mixtures of the tautomers (Ia) and (Ib).

The ratio in the mixture depends on factors which determine the state of aggregation, such as, for example, the temperature, solvent and concentration.

The new sulphonyliso(thio)urea derivatives of the formula (I) are obtained by an inventive process in which sulphonylguanidine derivatives of the formula (II) ##STR4## in which R¹, R² and M have the abovementioned meanings and

R^(1a) has the same meaning as R¹, but does not have to be identical to R¹ in each individual case and

R⁴ represents an optionally substituted hydrocarbon radical,

are reacted with compounds of the formula (III)

    M.sup.1 -X-R.sup.3                                         (III)

in which

X and R³ have the abovementioned meanings and

M¹ represents hydrogen or one equivalent of a metal,

if appropriate in the presence of bases and in the presence of diluents, and, if appropriate, the products of the formula (I) thereby obtained are treated with acids.

The new sulphonyliso(thio)urea derivatives of the formula (I) and their adducts with strong acids are distinguished by a powerful herbicidal activity.

Surprisingly, the new compounds of the formula (I) exhibit a considerably better herbicidal action than the already known isourea and isothiourea derivatives of the same type of action.

It is also to be regarded as surprising that the compounds according to the invention, of the formula (I), can be prepared by selective cleavage of sulphonylguanidine derivatives of the formula (II), since in addition to this novel reaction other cleavage reactions, for example as a result of attack at the sulphonyl groupings, would also have been expected.

The sulphonyl-guanidine derivatives of the formula (II) to be used as starting substances are the subject of a previous patent application (compare DE-OS (German Published Specification) No. 3,334,455 and EP-A-121, 082).

The compounds of the formula (II) are obtained--in the case where R¹ and R^(1a) are identical--by a process in which guanidine derivatives of the formula (IV) ##STR21## in which R² and R⁴ have the abovementioned meanings, are reacted with at least two molar equivalents of sulphonic acid chlorides of the formula (V)

    R.sup.1 --SO.sub.2 --Cl                                    (V)

in which R¹ has the abovementioned meaning, in the presence of acid acceptors, such as, for example, pyridine or diazabicyclooctane (DABCO), and if appropriate in the presence of diluents, such as, for example, methylene chloride or chloroform, at temperatures between -20° C. and +50° C., preferably at 0° C. to 30° C. Working up can be carried out in the customary manner, for example by addition of water, if appropriate acidification, for example with hydrochloric acid, extraction with a solvent which is virtually water-immiscible, such as, for example, methylene chloride or chloroform, washing of the organic phase with water, drying, filtration and concentration. The products of the formula (II) which thereby remain in the residue can in general be made to crystallise with organic solvents and, if appropriate, can be purified by recrystallisation. The compounds of the formula (II) thus obtained in which M represents hydrogen can be converted into corresponding salts of the formula (II)--M: metal equivalent--in the customary manner by reaction with metal compounds in suitable diluents, for example with sodium methylate in methanol.

The guanidine derivatives of the formula (IV) required as intermediates are also the subject of the abovementioned previous patent application (compare DE-OS (German Published Specification) No. 3,334,455).

These guanidine derivatives are obtained by a process in which cyanoamino compounds of the formula (VI)

    NC--NH--R.sup.2                                            (VI)

in which R² has the abovementioned meaning, are reacted with hydroxylamine derivatives of the formula (VII)

    H.sub.2 N--OR.sup.4                                        (VII)

in which R⁴ has the abovementioned meaning, or hydrochlorides thereof, if appropriate in the presence of diluents, such as, for example, ethanol or butanol, at temperatures between 20° C. and 150° C., preferably between 50° and 120° C., and, if appropriate, the products are then treated with acid acceptors, such as, for example, (aqueous) ammonia, sodium hydroxide or potassium carbonate. The guanidine derivatives (IV) are in general obtained here as crystals.

The cyanoamino compounds of the formula (VI) are known in some cases (compare J. Chem. Soc. 1953, 1725-1730). These compounds are essentially obtained by the following synthesis routes:

(1) in general by reaction of alkali metal or alkaline earth metal salts of cyanamide--such as, for example, sodium cyanamide or calcium cyanamide--with halogen compounds of the formula (VIII)

    Hal.sup.1 -R.sup.2                                         (VIII)

in which

R² has the abovementioned meaning and

Hal¹ represents fluorine, chlorine, bromine or iodine, in particular chlorine,

if appropriate in the presence of inert diluents, such as, for example, acetone, acetonitrile or dimethylformamide, at temperatures between 0° C. and 150° C., preferably between 10° C. and 100° C.; after the volatile component has been distilled off and the residue has been dissolved in water, the cyanoamino compounds of the formula (VI) can be precipitated by acidification, for example with hydrochloric acid, and isolated by filtration with suction; or

(2) in the case where R² represents a substituted pyrimidinyl radical, by reaction of cyanoguanidine ("dicyandiamide") with β-dicarbonyl compounds or if appropriate acetals or enol ethers thereof, such as, for example, acetylacetone (compare J. Chem. Soc. 1953, 1725-1730), acetoacetic acid esters (compare J. Prakt. Chem. 77, (1908), 542 and J. Chem. Soc. 1948, 586) or malonic acid esters (compare German patent specification No. 158,591). The 2-cyano-amino-4-hydroxy-6-methyl- or -4,6-dihydroxy-pyrimidines obtained from acetoacetic acid esters or malonic acid esters can be converted into the corresponding 2-cyanoamino-4-alkoxy-6-methyl- or -4,6-dialkoxy-pyrimidines in a known manner by reaction with alkylating agents, such as, for example, dimethyl sulphate or diethyl sulphate, if appropriate in the presence of diluents, such as, for example, water, methanol, ethanol, n- and iso-propanol, acetone, dioxane or dimethylformamide, and in the presence of acid-binding agents, such as, for example, sodium hydroxide, potassium hydroxide, sodium carbonate or potassium carbonate. To avoid N-alkylation, if appropriate, acylation is carried out with an acylating agent, such as, for example, acetic anhydride or acetyl chloride, and, after the alkylation, the product is deacylated again with aqueous acids or bases.

In another alternative process, the cyanoamino compounds of the formula (VI) are obtained by a process in which (3) amino compounds of the formula (IX)

    H.sub.2 N--R.sup.2                                         (IX)

in which R² has the abovementioned meaning, are reacted with carbonyl isothiocyanates of the formula (X) ##STR22## in which R³⁶ represents ethoxy or phenyl, if appropriate in the presence of an inert diluent, such as, for example, acetone, acetonitrile or toluene, at temperatures between 0° C. and 100° C., the resulting carbonylthioureas of the formula (XI) ##STR23## in which R³⁶ and R² have the abovementioned meanings, are isolated by filtration with suction, if appropriate after the mixture has been concentrated, and are reacted with aqueous alkali metal or alkaline earth metal hydroxide solutions, such as, for example, sodium hydroxide solution, if appropriate in the presence of an organic solvent, such as, for example, tetrahydrofuran or dioxane, at temperatures between 0° C. and 120° C., and the thioureas of the formula (XII) ##STR24## in which R² has the abovementioned meaning, which are obtained in crystalline form after acidification, for example with hydrochloric acid, are isolated by filtration with suction, and reacted with metal compounds which are capable of binding hydrogen sulphide, such as, for example, with lead (II) acetate, copper (II) acetate, mercury (II) acetate or iron (II) acetate, in the presence of aqueous alkali metal or alkaline earth metal hydroxide solutions, such as, for example, sodium hydroxide solution, at temperatures between 20° C. and 100° C., the mixture is filtered when the reaction is complete, and the filtrate is acidified with an acid, such as, for example, acetic acid. The products of the formula (VI) which are obtained in crystalline form in this procedure can be isolated by filtration with suction.

The starting substances for the preparation process, described above under (1), (2) and (3), for the cyanamino compounds of the formula (VI) are known and/or can be prepared by processes known per se.

These include the halogen compounds of the formula (VIII) (compare G 35, 28-30), the amino compounds of the formula (IX) (compare G 35, 31-2) and the carbonyl isothiocyanates of the formula (X) (compare J. Heterocycl. Chem 5 (1968, 837 and U.S. Pat. No. 4,160,037).

The hydroxylamine derivatives of the formula (VII) are known or they can be prepared by processes which are known per se (compare Chem. Pharm. Bull. 15 (1967), 345-349; Bull. Soc. Chim. France 1958, 664; and Synthesis 1976, 682).

The sulphonic acid chlorides of the formula (V) are known in some cases (compare Chemistry Lett. 1978, 951; European Published Application Nos. 23,422, 35,893, 42,731, 44,808, 44,809, 51,466, 64,804 and 70,041; U.S. Pat. Nos. 2,929,820, 4,282,242 and 4,372,778; J. Org. Chem. 33 (1968), 2104 and J. General Chem. 39 (1969), 2011).

These compounds are essentially obtained by the following two synthesis routes:

(1) by reaction of the corresponding sulphonic acids R¹ SO₃ H or alkali metal or alkaline earth metal salts thereof with halogenating agents, such as, for example, phosphorus-V chloride (phosphorus pentachloride), phosphoryl chloride (phosphorus oxychloride), thionyl chloride, phosgene or benzotrichloride, if appropriate in the presence of catalysts, such as, for example, pyridine or dimethylformamide, and if appropriate using inert diluents, such as, for example, methylene chloride, chloroform, acetonitrile, chlorobenzene and/or sulpholane, at temperatures between -20° C. and +150° C., preferably between 0° C. and +100° C.; after dilution with water, the sulphonic acid chlorides--if these are obtained as crystals--can be isolated by filtration with suction or can be purified by extraction with a water-immiscible solvent, such as, for example, methylene chloride, diethyl ether or hexane, washing and drying of the extracts, concentration and recrystallisation or distillation; or

(2) in a manner which is known per se (compare J. Org. Chem. 25 (1960), 1824; DE-OS (German Published Specification) No. 2,308,262 and European Published Application No. 59,241) by reaction of corresponding amino compounds R¹ -NH₂ with sodium nitrite and hydrochloric acid, if appropriate in the presence of acetic acid, at temperatures between -10° C. and +20° C., preferably between -5° C. and +10° C., and subsequently (in situ) with sulphur dioxide or a salt of sulphurous acid, such as, for example, sodium sulphite or sodium bisulphite, in the presence of a copper compound, such as, for example, copper chloride or copper sulphate, as the catalyst, at temperatures between 0° C. and 80° C., preferably between 10° C. and 60° C.

Working up can be effected in the customary manner: on dilution with water, the sulphonic acid chlorides are in general obtained as crystals and can be isolated by filtration with suction. However, they can also be extracted from the aqueous dispersion with a solvent which is virtually water-immiscible, such as, for example, methylene chloride or diethyl ether, dried, and purified by vacuum distillation.

The starting materials of the formula (II) are also obtained by a process in which monosulphonylguanidines of the formula (XIII) ##STR25## in which R¹, R² and R⁴ have the abovementioned meanings, are reacted with sulphonic acid chlorides of the formula (XIV)

    R.sup.1a --SO.sub.2 --Cl                                   (XIV)

in which R^(1a) has the abovementioned meaning, in the presence of acid acceptors, such as, for example, pyridine or diazabicylcooctane (DABCO), and if appropriate in the presence of diluents, such as, for example, methylene chloride, or chloroform, at temperatures between -20° C. and +50° C., preferably at 0° C. to +30° C. Working-up and, where relevant, conversion to metal compounds can be carried out as described above.

(e) In the case in which R¹ represents the radical ##STR29## wherein R³⁸ represents alkyl, by reaction of benzodisultams of the formula (XVIII) ##STR30## in which R² and R³⁸ have the abovementioned meanings, with compounds of the formula (VII)

    H.sub.2 N--OR.sup.4                                        (VII)

in which R⁴ has the abovementioned meaning, or their hydrochlorides, if appropriate in the presence of diluents, such as, for example, methanol or ethanol, at temperatures between 0° C. and 150° C., preferably between 20° C. and 100° C. The compounds of the formula (XIII) are obtained in general in crystalline form in this procedure.

The sulphonylisothiourea derivatives of the formula (XV) which are stated above as starting substances are known and/or can be prepared by processes which are known per se (compare EP-A 5,986).

The benzolactams of the formula (XVI) furthermore stated as starting substances are not known from the literature to date. Various benzolactam sultams form the subject of patent applications of the Applicant which do not form part of the published prior art (compare DE-OS (German Published Specifications) Nos. 3,431,915, 3,431,920 and 3,431,927). The benzolactam sultams of the formula (XVI) are obtained by reaction of guanidine derivatives of the formula (IV)--above--with 2-chlorosulphonyl-benzoyl chloride in the presence of acid acceptors, such as, for example, pyridine, and if appropriate in the presence of diluents, such as, for example, methylene chloride, at temperatures between -30° C. and +50° C., preferably between -10° C. and +30° C.

Particularly preferred starting substances of the formula (III) are those in which

The starting substances of the formula (III) are known products which are largely commercially available.

The preparation process according to the invention is preferably carried out using diluents. Possible diluents are virtually all the inert organic solvents, and if appropriate also water, mixed with these solvents. Particularly suitable alcohols, such as, for example, methanol, ethanol, n- or i-propanol and n-, i-, sec.- or tert.-butanol, ketones, such as, for example, acetone, methyl ethyl ketone or methyl isobutyl ketone, and furthermore acetonitrile, dimethylformamide and dimethylsulphoxide.

If appropriate, the process according to the invention is carried out using bases. Possible bases are virtually all the acid-binding agents which are usually employed. These include, in particular, metal hydroxides, carbonates, hydrides and alcoholates, such as, for example, the hydroxides of sodium, potassium and calcium, potassium carbonate, sodium hydride, calcium hydride, sodium methylate, ethylate or propylate, potassium methylate, ethylate or tert.-butylate and aluminium isopropylate.

The reaction temperatures can be varied within a substantial range in the process according to the invention. In general, the reaction is carried out at temperatures between 0° C. and 150° C., preferably between 10° C. and 100° C. The process according to the invention is in general carried out under normal pressure.

For carrying out the process according to the invention, in general between 1 and 3 moles, preferably between 1.1 and 2.0 moles, of hydroxy or mercapto compound, or salts thereof, of the formula (III) are employed per mole of sulphonylguanidine derivative of the formula (II). The reaction components are usually brought together at room temperature or with external cooling and the reaction mixture is stirred, if appropriate at elevated temperature, until the reaction has ended.

The new compounds are worked up and isolated by customary methods:

if the products of the formula (I) are obtained as metal salts, they in general crystallise out of the reaction solution and can be isolated directly by filtration with suction; otherwise, after concentration of the mixture, they can be made to crystallise by digestion with suitable organic solvents, such as, for example, ethanol or acetone. The corresponding salt-free compounds can in general be obtained from the salt-like products of the formula (I) by dispersion in water and acidification, for example with acetic acid. Alternatively, the salt-free products of the formula (I) can be obtained after concentration of the reaction mixture, if appropriate acidification of the residue, for example with hydrochloric acid, shaking with water and an organic solvent which is virtually water-immiscible, such as, for example, methylene chloride or chloroform, separating off the organic phase, drying, filtration and concentration, and can be made to crystallise with suitable organic solvents, such as, for example, toluene or ethanol.

The active compounds according to the invention can be used as defoliants, desiccants, agents for destroying broad-leaved plants and, especially, as weedkillers. By weeds, in the broadest sense, there are to be understood all plants which grow in locations where they are undesired. Whether the substances according to the invention act as total or selective herbicides depends essentially on the amount used.

The active compounds according to the invention can be used, for example, with the following plants:

Dicotyledon weeds of the genera: Sinapis, Lepidium, Galium, Stellaria, Matricaria, Anthemis, Galinsoga, Chenopodium, Urtica, Senecio, Amaranthus, Portulaca, Xanthium, Convolvulus, Ipomoea, Polygonum, Sesbania, Ambrosia, Cirsium, Carduus, Sonchus, Solanum, Rorippa, Rotala, Lindernia, Lamium, Veronica, Abutilon, Emex, Datura, Viola, Galeopsis, Papaver and Centaurea.

Dicotyledon cultures of the genera: Gossypium, Glycine, Beta, Daucus, Phaseolus, Pisum, Solanum, Linum, Ipomoea, Vicia, Nicotiana, Lycopersicon, Arachis, Brassica, Lactuca, Cucumis and Cucurbita.

Monocotyledon weeds of the genera: Echinochloa, Setaria, Panicum, Digitaria, Phleum, Poa, Festuca, Eleusine, Brachiaria, Lolium, Bromus, Avena, Cyperus, Sorghum, Agropyron, Cynodon, Monochoria, Fimbristylis, Sagittaria, Eleocharis, Scirpus, Paspalum, Ischaemum, Sphenoclea, Dactyloctenium, Agrostis, Alopecurus and Apera.

Monocotyledon cultures of the genera: Oryza, Zea, Triticum, Hordeum, Avena, Secale, Sorghum, Panicum, Saccharum, Ananas, Asparagus and Allium.

However, the use of the active compounds according to the invention is in no way restricted to these genera, but also extends in the same manner to other plants.

The compounds are suitable, depending on the concentration, for the total combating of weeds, for example on industrial terrain and rail tracks, and on paths and squares with or without tree plantings. Equally, the compounds can be employed for combating weeds in perennial cultures, for example afforestations, decorative tree plantings, orchards, vineyards, citrus groves, nut orchards, banana plantations, coffee plantations, tea plantations, rubber plantations, oil palm plantations, cocoa plantations, soft fruit plantings and hopfields, and for the selective combating of weeds in annual cultures.

The active compounds according to the invention can be used for selectively combating monocotyledon and dicotyledon weeds in monocotyledon and dicotyledon crops, such as, for example, soya bean, cotton, rice, cereals and maize.

The active compounds can be converted to the customary formulations, such as solutions, emulsions, wettable powders, suspensions, powders, dusting agents, pastes, soluble powders, granules, suspension-emulsion concentrates, natural and synthetic materials impregnated with active compound, and very fine capsules in polymeric substances.

These formulations are produced in known manner, for example by mixing the active compounds with extenders, that is liquid solvents and/or solid carriers, optionally with the use of surface-active agents, that is emulsifying agents and/or dispersing agents and/or foam-forming agents.

In the case of the use of water as an extender, organic solvents can, for example, also be used as auxiliary solvents. As liquid solvents, there are suitable in the main: aromatics, such as xylene, toluene or alkyl naphthalenes, chlorinated aromatics and chlorinated aliphatic hydrocarbons, such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons, such as cyclohexane or paraffins, for example petroleum fractions, mineral and vegetable oils, alcohols, such as butanol or glycol as well as their ethers and esters, ketones, such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents, such as dimethylformamide and dimethylsulphoxide, as well as water.

As solid carriers there are suitable: for example ammonium salts and ground natural minerals, such as kaolins, clays, talc chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and ground synthetic minerals, such as highly disperse silicic acid, alumina and silicates, as solid carriers for granules there are suitable: for example crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite and dolomite, as well as synthetic granules of inorganic and organic meals, and granules of organic material such as sawdust, coconut shells, maize cobs and tobacco stalks; as emulsifying and/or foam-forming agents there are suitable: for example non-ionic and anionic emulsifiers, such as polyoxyethylene-fatty acid esters, polyoxyethylene-fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkylsulphonates, alkylsulphates, arylsulphonates as well as albumin hydrolysation products; as dispersing agents there are suitable: for example lignin-sulphite waste liquors and methylcellulose.

Adhesives such as carboxymethylcellulose and natural and synthetic polymers in the form of powders, granules or latices, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, as well as natural phospholipids, such as cephalins and lecithins, and synthetic phospholipids, can be used in the formulations. Further additives can be mineral and vegetable oils.

It is possible to use colorants such as inorganic pigments, for example iron oxide, titanium oxide and Prussian Blue, and organic dyestuffs, such as alizarin dyestuffs, azo dyestuffs and metal phthalocyanine dyestuffs, and trace nutrients such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.

The formulations in general contain between 0.1 and 95 per cent by weight of active compound, preferably between 0.5 and 90%.

The active compounds according to the invention, as such or in the form of their formulations, can also be used, for combating weeds, as mixtures with known herbicides, a finished formulation or tank mix being possible.

The active compounds according to the invention can be applied by themselves and in combination with other active compounds. Possible mixing partners are: ureas (for example methabenzthiazuron, isoproturon, chlorotoluron and fluometuron), triazines (for example atrazine), triazinones (for example metribuzin, metamitron and 4-amino-6-tert.-butyl-3-ethylthio-1,2,4-triazin-5(4H)-one), triazinediones (for example ametridione), chloroacetamides (for example alachlor and metolachlor), cyclohexanediones (for example sethoxydim), heteroaryloxy-or aryloxy-phenoxypropionic acids (for example 2-(benzyloxy)-ethyl (2R)-2-[4-(3,5-dichloro-pyridyl-2-oxy)-phenoxy]-propionate and (trimethylsilyl)-methyl (2R)-2-[4-(3,5-dichloro-pyridyl-2-oxy)-phenoxy]-propionate, halogenoalkanecarboxylic acids (for example 2,4-D, 2,4-DP, MCPA and MCPP), diphenyl ethers (for example fomesafen and aclonifen), and furthermore bentazon and pyridazines (for example pyridate).

Mixtures with other known active compounds, such as fungicides, insecticides, acaricides, nematicides, bird repellants, plant nutrients and agents which improve soil structure, are also possible.

The active compounds can be used as such, in the form of their formulations or in the use forms prepared therefrom by further dilution, such as ready-to-use solutions, suspensions, emulsions, powders, pastes and granules. They are used in the customary manner, for example by watering, spraying, atomising or scattering.

The active compounds according to the invention can be applied either before or after emergence of the plants. They can also be incorporated into the soil before sowing.

The amount of active compound used can vary within a substantial range. It depends essentially on the nature of the desired effect. In general, the amounts used are between 0.001 and 15 kg of active compound per hectare of soil surface, preferably between 0.01 and 10 kg per ha.

The active compounds (I) according to the invention also exhibit fungicidal activity, for example activity against Pyricularia oryzae in rice and against scab fungi, for example apple scab.

The preparation and use of the active compounds according to the invention can be seen from the following examples.

PREPARATION OF STARTING SUBSTANCES OF THE FORMULA (II) Example (II-1) ##STR534##

A mixture of 29.4 g (0.15 mole) of N'-(4,6-dimethyl-pyrimidin-2-yl)-N"-methoxy-guanidine, 63.3 g (0.3 mole) of 2-chloro-benzenesulphonyl chloride and 150 ml of pyridine is stirred at 20° C. for 2 days. After substantial removal of the pyridine by distillation under a waterpump vacuum, 200 ml of water are added to the residue and the mixture is extracted with 200 ml of methylene chloride. The organic phase is separated off, dried and concentrated. The residue is made to crystallise by digestion with ethanol.

41.2 g (51% of theory) of N'-(4,6-dimethylpyrimidin-2-yl)-N"-methoxy-N",N'"-bis-(2-chloro-benzenesulphonyl)-guanidine of melting point 164° C. to 166° C. are obtained.

Example (II-2) ##STR535##

54 g (0.256 mole) of 2-chloro-benzenesulphonyl chloride are added dropwise, while stirring, to a mixture of 97 g (0.25 mole) of N'-(4-methoxy-6-methyl-s-triazin-2-yl)-N"-methoxy-N"'-(2-chloro-benzenesulphonyl)-guanidine and 300 ml of pyridine which has been cooled to -20° C. The reaction mixture is stirred for 15 hours at 20° C. and concentrated. The residue is taken up in 300 ml of methylene chloride, and this solution is washed with twice 150 ml of dilute hydrochloric acid, filtered and concentrated. The product obtained in crystalline form when the residue is triturated with ethanol is isolated by filtration with suction.

80 g (70% of theory) of N'-(4-methoxy-6-methyl-s-triazin-2-yl)-N"-methoxy-N", N"'-bis-(2-chloro-benzene-sulphonyl)-guanidine of melting point 164° C. are obtained.

Example (II-3) ##STR536##

2.5 g (0.012 mole) of 2-chloro-benzenesulphonyl chloride are added to a mixture of 5.0 g (0.011 mole) of N'-(4,6-dimethyl-pyrimidin-2-yl)-N"-methoxy-N"'-(2butylaminocarbonyl-benzenesulphonyl)-guanidine, 2.0 g (0.016 mole) of 4-dimethylamino-pyridine and 30 ml of acetonitrile. The reaction mixture is heated at the boil under reflux for 3 hours and then concentrated. The residue is taken up in 100 ml of methylene chloride. This solution is washed with 100 ml of 5% strength hydrochloric acid and with 100 ml of water, dried, filtered and concentrated.

1.8 g (30% of theory) of N'-(4,6-dimethyl-pyrimidin-2-yl)-N"-methoxy-N"-(2-chloro-benzenesulphonyl)-N"'-(2-butylaminocarbonyl-benzenesulphonyl)-guanidine are obtained as a crystalline residue of melting point 157° C.

PREPARATION OF STARTING SUBSTANCES OF THE FORMULA (IV) Example (IV-1) ##STR998##

A mixture of 109 g (0.67 mole) of 0-methyl-hydroxylamine hydrochloride, 99 g (0.67 mole) of 2-cyano-amino-4,6-dimethylpyrimidine and 600 ml of ethanol is heated at the boiling point under reflux for 7 hours. The alcohol is then distilled off under a waterpump vacuum, the residue is dissolved in hot water and this solution is added to 100 ml of concentrated ammonia. The product which has crystallised out is filtered off with suction and recrystallised from ethanol.

71.8 g (55% of theory) of N'-(4,6-dimethyl-pyrimidin-2-yl)-N''-methoxy-guanidine of melting point 134° C. to 136° C. are obtained.

PREPARATION OF THE STARTING SUBSTANCES OF THE FORMULA (XIII) Example (XIII-1) ##STR1080##

A solution of 16.8 g (0.15 mole) of diazabicyclooctane in 50 ml of methylene chloride is added dropwise with stirring to a mixture of 9.8 g (0.05 mole) of N'-(4,6-dimethyl-pyrimidin-2-yl)-N"-methoxy-guanidine, 28.2 g (0.12 mole) of 2-chlorophenyl-methanesulphonyl chloride and 50 ml of methylene chloride which has been cooled to 0° C. The reaction mixture is stirred for 2 hours at 10° C. and for a further 15 hours at 20° C. Thereafter, 50 ml of 2N hydrochloric acid are added, the mixture is shaken thoroughly and the organic phase is then separated off, washed with water, dried, filtered and concentrated. The oily residue is brought to crystallisation with isopropanol.

3.0 g (12% of theory) of N'-(4,6-dimethyl-pyrimidin-2-yl)-N"-methoxy-N"'-(2-chloro-benzenesulphonyl)-guanidine of melting point 130° C. are obtained.

Example (XIII-2) ##STR1081##

A mixture of 13.8 g (0.025 mole) of N'-(4,6-dimethyl-pyrimidin-2-yl)-N"-methoxy-N",N"'-bis-(2-chloro-benzenesulphonyl)-guanidine, 3.7 g (0.026 mole) of O-octyl-hydroxylamine and 80 ml of ethanol is heated at the boil under reflux for 15 hours. Thereafter, the mixture is concentrated in a water pump vacuum, and the product is brought to crystallisation by trituration and is isolated by filtration with suction.

3.2 g (27% of theory) of N'-(4,6-dimethyl-pyrimidin-2-yl)-N"-octyloxy-N"'-(2-chloro-benzenesulphonyl)-guanidine of melting point 55° C. are obtained.

Example (XIII-3) ##STR1082##

4.0 g (0.025 mole) of butylamine are added at 20° C.-30° C. with stirring to a mixture of 9.1 g (0.025) mole of the compound of the formula below ##STR1083## and 60 ml of diethyl ether and 5 ml of dioxane.

PREPARATION OF STARTING SUBSTANCES OF THE FORMULA (XV) Example (XV-1) ##STR1240##

11 g (0.4 mole) of sodium hydride (80% strength) are added in portions to a suspension of 31.2 g (0.2 mole) of 2-amino-4,6-dimethoxy-s-triazine in 200 ml of tetrahydrofuran at 20° C. After the mixture has been stirred for 12 hours, 60 g (0.2 mole) of N-(2-chloro-benzensulphonyl)-S',S"-dimethyl-iminodithiocarbonic acid ester are added, the reaction temperature increasing to 60° C. The reaction mixture is stirred for 5 hours at 20° C., diluted with 800 ml of water and filtered. After the mixture has been acidified with concentrated hydrochloric acid, the product crystallises, and is isolated by filtration with suction.

42 g (48% of theory) of N'-(4,6-dimethoxy-s-triazin-2-yl)-N"-(2-chloro-benzenesulphonyl)-S-methyl-isothiourea of melting point 176° C. are obtained.
